The 1 Cor. 6:12, 13 seem to relate to that early dispute among Christians about the distinction of meats, and yet to be prefatory to the caution that follows against fornication. The connection seems plain enough if we attend to the famous determination of the apostles, Acts 15:19-29, where the prohibition of certain foods was joined with that of fornication. Now some among the Corinthians seem to have imagined that they were as much at liberty in the point of fornication as of meats, especially because it was not a sin condemned by the laws of their country. They were ready to say, even in the case of fornication, All things are lawful for me. This pernicious conceit Paul here sets himself to oppose: he tells them that many things lawful in themselves were not expedient at certain times, and under particular circumstances; and Christians should not barely consider what is in itself lawful to be done, but what is fit for them to do, considering their profession, character, relations, and hopes: they should be very careful that by carrying this maxim too far they be not brought into bondage, either to a crafty deceiver or a carnal inclination. All things are lawful for me, says he, but I will not be brought under the power of any, 1 Cor. 6:12. Even in lawful things, he would not be subject to the impositions of a usurped authority: so far was he from apprehending that in the things of God it was lawful for any power on earth to impose its own sentiments. Note, There is a liberty wherewith Christ has made us free, in which we must stand fast. But surely he would never carry this liberty so far as to put himself into the power of any bodily appetite. Though all meats were supposed lawful, he would not become a glutton nor a drunkard. And much less would he abuse the maxim of lawful liberty to countenance the sin of fornication, which, though it might be allowed by the Corinthian laws, was a trespass upon the law of nature, and utterly unbecoming a Christian. He would not abuse this maxim about eating and drinking to encourage any intemperance, nor indulge a carnal appetite: “Though meats are for the belly and the belly for meats (1 Cor. 6:13), though the belly was made to receive food, and food was originally ordained to fill the belly, yet if it be not convenient for me, and much more if it be inconvenient, and likely to enslave me, if I am in danger of being subjected to my belly and appetite, I will abstain. But God shall destroy both it and them, at least as to their mutual relation. There is a time coming when the human body will need no further recruits of food.” Some of the ancients suppose that this is to be understood of abolishing the belly as well as the food; and that though the same body will be raised at the great day, yet not with all the same members, some being utterly unnecessary in a future state, as the belly for instance, when the man is never to hunger, nor thirst, nor eat, nor drink more. But, whether this be true or no, there is a time coming when the need and use of food shall be abolished. Note, The expectation we have of being without bodily appetites in a future life is a very good argument against being under their power in the present life. This seems to me the sense of the apostle’s argument; and that this passage is plainly to be connected with his caution against fornication, though some make it a part of the former argument against litigious law-suits, especially before heathen magistrates and the enemies of true religion. These suppose that the apostle argues that though it may be lawful to claim our rights yet it is not always expedient, and it is utterly unfit for Christians to put themselves into the power of infidel judges, lawyers, and solicitors, on these accounts. But this connection seems not so natural. The transition to his arguments against fornication, as I have laid it, seems very natural: But the body is not for fornication, but for the Lord, and the Lord for the body, 1 Cor. 6:13. Meats and the belly are for one another; not so fornication and the body.
I. The body is not for fornication, but for the Lord. This is the first argument he uses against this sin, for which the heathen inhabitants of Corinth were infamous, and the converts to Christianity retained too favourable an opinion of it. It is making things to cross their intention and use. The body is not for fornication; it was never formed for any such purpose, but for the Lord, for the service and honour of God. It is to be an instrument of righteousness to holiness (Rom. 6:19), and therefore is never to be made an instrument of uncleanness. It is to be a member of Christ, and therefore must not be made the member of a harlot, 1 Cor. 6:15. And the Lord is for the body, that is, as some think, Christ is to be Lord of the body, to have property in it and dominion over it, having assumed a body and been made to partake of our nature, that he might be head of his church, and head over all things, Heb. 2:5, 18. Note, We must take care that we do not use what belongs to Christ as if it were our own, and much less to his dishonour.
II. Some understand this last passage, The Lord is for the body, thus: He is for its resurrection and glorification, according to what follows, 1 Cor. 6:14; which is a second argument against this sin, the honour intended to be put on our bodies: God hath both raised up our Lord, and will raise us up by his power (1 Cor. 6:14), by the power of him who shall change our vile body, and make it like to his glorious body by that power whereby he is able to subdue all things to himself, Phil. 3:21. It is an honour done to the body that Jesus Christ was raised from the dead: and it will be an honour to our bodies that they will be raised. Let us not abuse those bodies by sin, and make them vile, which, if they be kept pure, shall, notwithstanding their present vileness, be made like to Christ’s glorious body. Note, The hopes of a resurrection to glory should restrain Christians from dishonouring their bodies by fleshly lusts.
III. A third argument is the honour already put on them: Know you not that your bodies are the members of Christ? 1 Cor. 6:15. If the soul be united to Christ by faith, the whole man is become a member of his mystical body. The body is in union with Christ as well as the soul. How honourable is this to the Christian! His very flesh is a part of the mystical body of Christ. Note, It is good to know in what honourable relations we stand, that we may endeavour to become them. But now, says the apostle, shall I take the members of Christ, and make them the members of a harlot? God forbid. Or, take away the members of Christ? Would not this be a gross abuse, and the most notorious injury? Would it not be dishonouring Christ, and dishonouring ourselves to the very last degree? What, make a Christ’s members the members of a harlot, prostitute them to so vile a purpose! The thought is to be abhorred. God forbid. Know you not that he who is joined to a harlot is one body with hers? For two, says he, shall be one flesh. But he who is joined to the Lord is one spirit, 1 Cor. 6:16, 17. Nothing can stand in greater opposition to the honourable relations and alliances of a Christian man than this sin. He is joined to the Lord in union with Christ, and made partaker by faith of his Spirit. One spirit lives and breathes and moves in the head and members. Christ and his faithful disciples are one, John 17:21, 22. But he that is joined to a harlot is one body, for two shall be one flesh, by carnal conjunction, which was ordained of God only to be in a married state. Now shall one in so close a union with Christ as to be one spirit with him yet be so united to a harlot as to become one flesh with her? Were not this a vile attempt to make a union between Christ and harlots? And can a greater indignity he offered to him or ourselves? Can any thing be more inconsistent with our profession or relation? Note, The sin of fornication is a great injury in a Christian to his head and lord, and a great reproach and blot on his profession. It is no wonder therefore that the apostle should say, “Flee fornication (1 Cor. 6:18), avoid it, keep out of the reach of temptations to it, of provoking objects. Direct the eyes and mind to other things and thoughts.” Alia vitia pugnando, sola libido fugiendo vincitur—Other vices may be conquered in fight, this only by flight; so speak many of the fathers.
IV. A fourth argument is that it is a sin against our own bodies. Every sin that a man does is without the body; he that committeth fornication sinneth against his own body (1 Cor. 6:18); every sin, that is, every other sin, every external act of sin besides, is without the body. It is not so much an abuse of the body as of somewhat else, as of wine by the drunkard, food by the glutton, etc. Nor does it give the power of the body to another person. Nor does it so much tend to the reproach of the body and render it vile. This sin is in a peculiar manner styled uncleanness, pollution, because no sin has so much external turpitude in it, especially in a Christian. He sins against his own body; he defiles it, he degrades it, making it one with the body of that vile creature with whom he sins. He casts vile reproach on what he Redeemer has dignifies to the last degree by taking it into union with himself. Note, We should not make our present vile bodies more vile by sinning against them.
V. The fifth argument against this sin is that the bodies of Christians are the temples of the Holy Ghost which is in them, and which they have of God, 1 Cor. 6:19. He that is joined to Christ is one spirit. He is yielded up to him, is consecrated thereby, and set apart for his use, and is hereupon possessed, and occupied, and inhabited, by his Holy Spirit. This is the proper notion of a temple—a place where God dwells, and sacred to his use, by his own claim and his creature’s surrender. Such temples real Christians are of the Holy Ghost. Must he not therefore be God? But the inference is plain that hence we are not our own. We are yielded up to God, and possessed by and for God; nay, and this is virtue of a purchase made of us: You are bought with a price. In short, our bodies were made for God, they were purchased for him. If we are Christians indeed they are yielded to him, and he inhabits and occupies them by his Spirit: so that our bodies are not our own, but his. And shall we desecrate his temple, defile it, prostitute it, and offer it up to the use and service of a harlot? Horrid sacrilege! This is robbing God in the worst sense. Note, The temple of the Holy Ghost must be kept holy. Our bodies must be kept as his whose they are, and fit for his use and residence.
VI. The apostle argues from the obligation we are under to glorify God both with our body and spirit, which are his, 1 Cor. 6:20. He made both, he bought both, and therefore both belong to him and should be used and employed for him, and therefore should not be defiled, alienated from him, and prostituted by us. No, they must be kept as vessels fitted for our Master’s use. We must look upon our whole selves as holy to the Lord, and must use our bodies as property which belongs to him and is sacred to his use and service. We are to honour him with our bodies and spirits, which are his; and therefore, surely, must abstain from fornication; and not only from the outward act, but from the adultery of the heart, as our Lord calls it, Matt. 5:28. Body and spirit are to be kept clean, that God may be honoured by both. But God is dishonoured when either is defiled by so beastly a sin. Therefore flee fornication, nay, and every sin. Use your bodies for the glory and service of their Lord and Maker. Note, We are not proprietors of ourselves, nor have power over ourselves, and therefore should not use ourselves according to our own pleasure, but according to his will, and for his glory, whose we are, and whom we should serve, Acts 27:23.
